DEVICE FOR HOLDING LOOSE OR REMOVABLE SHEETS OF PAPER BOOKWISE.

SPECIFICATION forming part of Letters Patent No. 760,359, dated May 17,1904.

Application filed November 3, 1902. Serial No. 129,944. (No model.)

Be it known that I, RALPH G. WHITLOGK, a citizen of the United States,residing at No. 1130 West Eighth street, in the city of Los Angeles, inthe county of Los Angeles and State of California, have invented acertain new and useful Improvement in Devices for Holding Loose orRemovable Sheets of Paper Book- Wise, of which the following is a full,clear, and exact description or specification, reference being had tothe annexed sheet of drawings and to the letters marked thereon.

This invention, which relates to certain improvements in devices forholding together or retaining loose or removable leaves or sheets ofpaper bookwise, is a further development of a certain part of thedevices for the same purpose described and shown in the specificationand drawings of my former applications for Letters Patent filed on thefollowing dates: July 5, 1902, September 24, 1902, and October 14, 1902,and having the following serial numbers, respectively: 114,346, 124,652,127,296.

tongue for each retainer, each tongue thereof passing through a hole inthe opening end of each retainer and through one or more correspondingholes in the back of the device.

Upon the annexed drawings, Figure 1 is a plan of the central part of adevice for holding loose or removable sheets of paper bookwise. Fig. 2is an end elevation corresponding to Fig. 1. Fig. 3 is another plan ofthe central part of a device for holding loose or removable sheets ofpaper bookwise. Fig. 4 is an end elevation of the same. Fig. 5 is a planof the central part of a device for holding loose or removable sheets ofpaper bookwise, having a curved back. Fig. 6 is an end tion.

and rod for operating said tongues into and out of the holes in theopening end of the retainers. (Shown at Figs. 5, 6, and 7.)

In the whole 'of the drawings that which constitutes my presentimprovement is identical; but for the purpose of clearly conveying tothe intelligence of others the essential feature of invention in thewhole of the figures of drawings it is here explained that the drawingsillustrate how the improved retainers are applied to and renderedoperative in the other parts of loose-paper-holding devices of more thanone construction.

As shown by Figs. 1 to 4 of the drawings,

each retainer is marked A, and these are attached pivotally or hingewiseat one end thereof by pivots or pins a to one side or edge of the backmembers B. In the opposite ends of each retainer A a hole 0 is formed,which when the retainer A is closed down becomes coincident with theholes 7) in the metal of the opposite side or edge of the back 'part B.In Figs. 1 to 4 the sliding bolt G, having tongues d at one sidethereof, operates to hold the retainers Ain either the open or closedposition by the said bolts (1, with their tongues d, being slid into theholes 7) and c or by being withdrawn from the said holes I) and c. Thesliding tongues d in Figs. 5, 6, 7, 8, and 9 operate in a direction atright angles to that of the tongues (Z in Figs. 1 to, 4, this beingnecessary by reason of the retainers A in Figs. and 6 being attached toa curved back 13 in said Figs. 5 and 6 instead of to a flat back B, asin Figs. 1 to 4. In Figs. 5 and 6 the tongues d are operated by thecrank-rod f, and each tongue (2 is connected to each crank e, as shownat Figs. 5 to 9. Therefore from this construction it follows that bymoving the rod feircularly through a sufficient angle the severaltongues (Z are either moved into or out of the holes Z) and c, and theretainers A are thereby either loosened or fastened at will for thepurpose of removing papers from the retainers or for placing papersthereon, as may be required, it being explained that each sheet ofpapersuch as those marked E in Figs. 1, 2, 3, 4, 5, 6, and 7 isperforated or punched with holes at one edge thereof to enable the saidsheets of paper E to be passed over or upon or removed from the severalretainers A A. The holes Z) and b are provided by forming eyes along theedge of the back.

Having now described the nature of my said invention and thebest system,mode, or man ner' I am at present acquainted with for carrying the sameinto practical effect, I desire to observe in conclusion that what Iconsider to be novel and original, and therefore claim as the inventionto be secured to me by Letters Patent, is as follows:

1. In a device for holding loose sheets, in combination, the cover, acurved retainer pivoted at one edge of the back and having its oppositeend directed downwardly to the opposite edge of the back, a slidingtongue and means for operating the said tongue, said means extendinglongitudinally of the back, said retainer at its free end and the edgeof the back adjacent the said free end being provided with openings toreceive thesliding" tongue, substantially as described.

2. In a device for holding or containing loose or removable sheets ofpaper bookwise, the combination of the curved retainer, the hinged orpivoted connection of the curved retainer to the cover, the sliding boltwith tongues the latter passing into holes in the opening ends of theretainer and the corresponding side or edge of the device, and thecovers of the said device, the retainers and corresponding side or edgehaving holes for receiving the tongues, substantially as hereinbeforedescribed.-

In testimony whereof I have hereunto set my hand and seal, this 15th dayof October, A. D. 1902, in the presence of two subscribing witnesses.
